REPAIR DEVICE FOR TIRES- Specification of Letters Patent.

Patented June 12, 1906.

Application filed December '7 1905. Serial 110.290,?345.

To all whom it may concern.-

Be it known that 1, JOHN R. VOSBURGH, a citizen of the United States,residing at J olmstown in the county of Fulton and State of New York,have invented certain new and useful Improvements in Repair Devices forTires, and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in tire repairdevices, and more particularly to those of the metal type.

The object of my said invention is to simplify the construction of thisclass of devices and at the same time so construct the same that theycan be more readily applied to the puncture or cut in the tire thanthose heretofore produced.

In the accompanying drawings I have clearly illustrated my invention,and a full and exact description thereof is contained in the annexedspecification.

In the drawings, Figure l is a perspective view of my improved repairdevice. Fig. 2 is a perspective view of the same, showing the partsseparated. Fig. 3 is a perspective view showing the device partiallyinserted in a puncture or cut in the tire. Fig. 4 is a sectional view ofa tire, showing my device applied to a cut therein before the repair hasbeen completed. Fig.- 5 is a view similar to Fig. 4, showing the repaircompleted; and Fig. 6 is a modification of my device.

In the several views like letters of reference designate similar partsof my improved device.

A in the drawings designates a shank constructed of wire or the like,preferably of brass, and so bent that the portions a and a will extendin opposite directions and at approximately right angles to the portion(L The portion a is provided at its end with a curved portion or arm aextending at right angles to the portion a and the portion a isscrew-threaded and provided at its end with the enlargement a providedwith the flattened portion (L5.

B is the inner clamping-plate, preferably brass and of elliptical shape,and is provided with the orifice b to enable the same to be slipped ontothe shank A, said plate being adapted to bear upon the portion a of thev enlargement a*. Plate B may be bent to conform to the curve of thetire.

O is the outer clamping-plate, also preferably of brass and circular inform, and is provided with an orifice c, threaded corresponding with theportion a. This plate C may also be made to conform with the curve ofthe tire, if desired.

In Fig. 6 I have illustrated a sli ht modification, the only differencebeing t at in this construction I preferably enlarge the portion a, andinstead of the flat surface a I preferably round the enlargement a, asat a, and countersink the plate B at b to fit the rounded portion a ofthe enlargement.

From the foregoing description the operation of my device is obvious andis as follows:

The plate B is first placed upon the portion a of the shank, which givesthe plate a vertical position/practically parallel to the portions itand a of the shank, as shown in Fig. 3, the plate being turned so thatthe lower point thereof will be in line with the portion a of the shank.With th s arrangement the plate and portion a of the shank may be"gripped between the thumb and first finger or gripped by pincers or thelike, the portion a preventing the shank from turning or wabbling,whereby the plate may be readily inserted in the puncture or cut in thetire. To facilitate the insertion of the plate, the same may be dippedin cement, which forms a slippery coating therefor. The plate havingbeen inserted in the tire, more cement is then forced into the cut andonto the plate, after which the shank is drawn through the plate untilthe fiat portion 0. of the enlargement (1 engages the under side of theplate, and then the plate is drawn up against the inner surface of thetire, as shown in Fig. 4. The clamping-plate O is then placed upon theshank and screwed down on the portion a until it bears upon the tiresufiiciently hard to prevent it from turning, cement having first beenplaced upon the inner side thereof, after which the shank may be grippedby the portion a and turned until the plate C is forced down flush withthe tire and the escapement of air from the puncture is prevented. Theshank A is then sawed off flush with the top of the plate O and may, ifdesirable, be headed, thus completing the re air.

t is obvious that the operation of the modification is substantially thesame as that described. i 1

What I claim, and desire to secure by Letters Patent, is

1. In a tire repair device, the combination with a shank having aportion angularly disosed to other portions, of an inner clamp mg-plateprovided with an orifice adapted to loosely embrace said shank to permitfree movement of said plate longitudinally of said shank, a retainingdevice on one end of said shank, an exterior clamping-plate providedwith an orifice and adapted to fit onto said shank and means forclamping the tire between said plates, substantially as described.

2. In a tire repair device, the combination with a shank having aportion angularly disposed to other portions, a retaining device on oneend of the shank, a portion of said shank adjacent said retaining devicebeing screwthreaded, aninner clampin -plate provided with an orificeadapted to Ioosely embrace said shank to ermit the free movement of saidplate longitudinally of said shank, and an exterior clamping-plateprovided with an internallythreaded orifice corresponding with saidthreaded portion of the shank, substantially as described.

3. In a tire repair device, the combination with a shank having aportion angularly disposed to other portions, a retaining device on oneend of the shank, a portion of said shank adjacent to said retainingdevice being screwthreaded, an inner clamping-plate provided with anorifice adapted to loosely embrace Y said shank to permit the freemovement of said plate longitudinally of said shank, an exterior claming-plate provided with an orifice interna ly threaded correspondinglywith said threaded ortion of the shankand means whereby sai shank can beturned to draw said plates together, substantially as described.

4;. I11 a tire repair device, the combination with a shank having aportion angularly disposed to other portions, a retaining device on oneend of the shank, a portion of said shank adjacent to said retainingdevice being screwthreaded, an inner clamping-plate provided with anorifice ada ted to loosely embrace said shank to permit the freemovement of said plate longitudinally of said shank, an exteriorclamping-plate provided with an orifice internally threadedcorrespondingly with said threaded portion of the shank and an arm onsaid shank whereby the same can be turned to draw said clamping-platestogether, substantially as described.

5. In a tire repair device, the combination with a shank having aportion angularly disposed to other portions, a retaining device on oneend of the shank, a portion of said shank adjacent to said retainingdevice being screwthreaded, an inner clamping-plate provided with anorifice adapted to loosely embrace said shank to permit the freemovement of said late longitudinally of said shank, an exteriorclamping-plate provided with an orifice internally threadedcorrespondingly with said threaded portion of the shank and an arm onsaid shank extending in a plane perpendicular to said angular portion ofsaid shank, substantially as described.

6. In a tire repair device, the combination with a shank having itsintermediate portion bent at an angle to its ends, an arm on said shankangularly disposed to said intermediate portion, a retaining device onone end of said shank, a portion of said shank adjacent to saidretaining device being screwthreaded, an inner clamping-plate providedwith an orifice adapted to loosely embrace said shank to platelongitudinally of said shank and an outer clamping-plate provided withan orifice internally threaded correspondingly with said threadedportion of the shank, substantially as described.

In testimony whereof I affix my signature in the presence of twowitnesses.
